Minnesota Vikings OT Matt Kalil said he was surgery-free this offseason for the first time since 2013. Kalil said this is the earliest he's worked out in a long time and he's getting stronger every day, adding that it feels good not having to play catch-up going into training camp.

Minnesota Vikings OT T.J. Clemmings, who started all 16 games at right tackle last season, will move to left tackle to serve as the backup to OT Matt Kalil, according to head coach Mike Zimmer. Kalil is entering the final year of his contract and the team had a logjam at right tackle due to the free-agent signing of OT Andre Smith and the return of OT Phil Loadholt, who missed the entire 2015 season with a torn Achilles' tendon.

Minnesota Vikings OT Matt Kalil is expected to be retained by the Vikings, who will pick up his $11.1 million fifth-year option, according to a league source. The team could opt to sign him to an extension to reduce the salary cap hit.

Minnesota Vikings OT Matt Kalil (knees) is already doing extra footwork drills in training camp after undergoing two knee surgeries this spring. Kalil said his health is no longer the first thing on his mind, and he's having fun playing football again. Kalil was terrible last season because of his health, and QB Teddy Bridgewater was pressured 29.9% of the time. "I'm stronger, bigger. I'm quick again on my feet," Kalil said. "It's about getting that back. It's just a year of bad technique -- you've kind of got to break all those habits. But it's going along well."

Minnesota Vikings OT Matt Kalil (knees) underwent arthroscopic surgery on both knees in January and received injections designed to help patients deal with joint pain in March, two people with knowledge of the procedures told USA TODAY Sports. Kalil has had knee troubles the last two seasons.

Minnesota Vikings OT Matt Kalil (knee) said he does not know how much he will be able to do during the mandatory minicamp next week but should be ready for the start of training camp.

Minnesota Vikings C John Sullivan (ankle) signed a five-year, $25.1 million contract extension in December 2011, and he erased any doubt in 2012 when he ascended among the NFL's elite centers. He played all 1,097 snaps despite battling an ankle injury which hampered him early in the season. He developed into a leader, and just missed out on a Pro Bowl selection and a $500,000 escalator as a result. Sullivan and OT Matt Kalil are expected to be fixtures for many years to come.
